Exodus 6:5-7 New Revised Standard Version Catholic Edition (NRSVCE)
5 I have also heard the groaning of the Israelites whom the Egyptians are holding as slaves, and I have remembered my covenant. 6 Say therefore to the Israelites, ‘I am the Lord, and I will free you from the burdens of the Egyptians and deliver you from slavery to them. I will redeem you with an outstretched arm and with mighty acts of judgment. 7 I will take you as my people, and I will be your God. You shall know that I am the Lord your God, who has freed you from the burdens of the Egyptians.
